R-29RMU missile

R-29RMU is an updated R-29RM missile. The development resulted in its increased resistance to damage effects of a nuclear explosion; a possibility to fire from high Arctic latitudes; firing along flat trajectories with short time of flying to a target; a four-unit MIRV of the middle power class that can be refitted with a ten-unit warhead of the low power class. The R-29RMU is placed (along with the R-29RM missile) aboard the 667BDRM submarines.
